Flex connect between branch and HQ

[amaoxrebeli]

In my scenario I need to connect Access Points fron branch office in VLAN2 to WLC in HQ in VLAN1.

There is an IPSec tunnel betweeen these sites and WLC can ping AP-s on remote branch site and vise-versa.

Here is my question:

1) I do need to define a native vlan for branch flex connect group where branch APs reside in right?
2) If i do so, I will need to allow VLAN2(branch) on the trunk port of WLC?
3) There is no VLAN2 in HQ switching table, so if I create it, there will be no point in it right? it wont be the same VLAN2 as VLAN2 in branch office?
4) So, how do I pass through VLAN2 to HQ?

Native vlan in hq "wlc" use for managment interface of wlc

Native vlan for ap in site use for ip address of ap.

Two different native vlan in two different location one in ap and other in wlc"hq".

So, HQ: Native Vlan ID (in flex connect config) = HQ native vlan id

Branch: AP = native vlan for branch

how about Wlan to Vlan mapping?

I have WLAN CORPNET in hq and i want same WLAN in branch as well.

WLAN CORPNET Id = VLAN CORPNET branch ID?
